Thanks for the feedback and playing! The dark matter recipe bug should now be patched in v0.4.4
Quota exceeded is an itch.io/browser issue (too much data saved since you have so many factories, i.e. your factory setup is too OP XD) but stems from lack of performance optimization, which will not be addressed until later, after full gameplay loop features are in.
Thanks for the suggestion on how to optimize! Will give it more thought when the time comes
